Canada Gas Tax Holiday Extended to 2027: New Dates and What It Means for Gas Prices

Canada’s gas tax holiday has been extended. It was due to end on Monday 7 September 2026, with the federal fuel excise tax returning the next day. On Wednesday 2 September, Finance Minister François-Philippe Champagne announced in Ottawa that the suspension runs on into the new year instead.

The tax adds 10 cents a litre to gasoline and 4 cents to diesel. Because sales tax is charged on top of it, the tax line on your receipt rises by a bit more than that.

When does the gas tax break end?

Not on 8 September any more. The full suspension now runs to the end of January 2027, and the tax returns in stages after that.

The staged return is what Champagne set out on 2 September: the tax stays fully suspended into the new year, comes back at 50% of the normal rate in February and March 2027, and returns to normal in April 2027. The government put the total cost of the holiday at $5.3 billion in forgone revenue.

The wording of the ORIGINAL order was narrower than “ends in September”: it covered fuel for which the tax becomes payable after 19 April 2026 and before 8 September 2026. That end date is the one the 2 September extension moves; the mechanism it describes still applies, because the tax attaches where it becomes payable in the supply chain. The tax attaches at the point it becomes payable in the supply chain, not at the moment you hold the nozzle.

How much does the tax add back?

Ten cents a litre on gasoline and four cents on diesel — the same rates that applied before April.

Neither rate is new, and neither is rising. The 10-cent gasoline rate has been in place since 1995; the 4-cent diesel rate since 1987. What happened in April was a temporary suspension to zero, and what happens on 8 September is a return to the long-standing rate.

Why is the increase more than 10 cents?

Because GST or HST is charged on the full pump price, and the excise tax is part of that price. Sales tax is applied on top of a tax.

The federal government is explicit about the base: GST/HST is charged on crude oil, refining and marketing costs and margins, the federal excise tax, applicable carbon levies, and provincial road taxes. The excise sits inside the amount that sales tax is calculated on, which is why removing it saved slightly more than 10 cents and restoring it costs slightly more than 10 cents.

What about provincial fuel taxes?

They are not changing. Only the federal layer moves on 8 September — and the provincial layer is much larger in some places than the federal one.

The British Columbia figures include regional transit levies, which is why the province appears three times at three different rates.

A driver in the Vancouver area pays more than four times the provincial fuel tax of a driver in Yukon, and none of that is affected by what happens on 8 September. There are also provincial clean-fuel adjusters on top in several provinces.

Will pump prices go up by that much when the tax returns?

The tax component will. The price on the sign is a different question, and this page does not answer it.

Here is the honest split:

• What is certain: when it returns in full, the federal excise line is 10 cents on gasoline and 4 cents on diesel, and sales tax applies on top, so the tax portion of a litre rises by roughly 10.5 to 11.5 cents depending on where you are.
• What is not: the wholesale price of fuel moves daily for reasons that have nothing to do with this tax. A pump price is the wholesale cost plus margins plus every tax layer, and two of those three move on their own.

So “the tax adds about 11 cents at the full rate” is a fact, and “gas will cost about 11 cents more the day it returns” is not. They are only the same sentence if nothing else changes, and something else always changes.

What this article does not do

• It does not forecast fuel prices — not ours, and not anyone else’s outlook or target.
• It does not tell you when to fill up. The arithmetic is above; the decision is yours and depends on prices you can see and we cannot.
• The extension is reported, not yet published as law. Champagne announced it in Ottawa on 2 September 2026 and it was carried by CBC, the Canadian Press and BNN Bloomberg. The staged return — half rate in February and March 2027, full rate from April — comes from that announcement. The enabling order had not been published when this page was updated, so if the legal wording differs from the announcement, the wording governs.

If the arithmetic above matters to your budget, the lever you actually control is where you fill up — we keep a guide to finding cheap gas near you and stacking cash back . For how fuel costs get used in politics rather than budgets, see our piece on gas prices and the 2028 US race .

What to take from it

• 8 September is the date. 7 September is the last day without the tax.
• 10 cents gasoline, 4 cents diesel — and both rates are decades old, not new.
• The tax line moves by 10.5–11.5 cents, not exactly 10, because sales tax rides on top.
• Your province matters more than the federal tax does. From 6.2 cents in Yukon to 27 in Metro Vancouver, and none of it changes in September.
• Nobody can tell you the pump price on 8 September, including us.
